Description

Vacuum film-pressing type III-class function regulator

Technical Field

The invention belongs to the field of orthodontic treatment, and particularly relates to a vacuum squeeze-film type III-class function regulator.

Background

The type III of Anderson malocclusion is one of the most common children malocclusion deformities, which can cause the children to develop malformation of the maxillofacial region and even influence the mental health of the children. The etiology of the class III wrong teeth complex deformity of Anderson is complex, most scholars at home and abroad think that the influencing factors can be divided into 2 aspects of genetic factors and environmental factors or the result of the combined action of the genetic factors and the environmental factors at present, and the class III wrong teeth complex deformity belongs to polygenic genetic diseases.

The main characteristics are that the anterior teeth are in reverse occlusion, and the molar mesial relationship may be accompanied by the posterior teeth in reverse occlusion. In addition to typical contra-occlusal deformities, class III malocclusions may be characterized by a flat face, sharp nasolabial angle, collapsed upper lip, concave face due to underdevelopment or retroreduction of the upper jaw; it also can be made into the form of protrusion of the mandible (clinically named as type III face) due to excessive growth of the mandible, long and short mandible, blunt mandible angle, and outward turning of the lower lip. The incidence rate of Chinese class III malocclusion deformity is about 12 percent, which is one of the most common dentognathic deformities in orthodontics.

The conventional FR-III functional appliance has the disadvantages of complex manufacturing process, relatively high time cost, difficult maintenance after damage and no effect of correcting bad breath habits. The MRC appliance is a finished appliance, cannot be customized according to the personal condition of a patient, is made of a relatively fixed material with too soft size, is not favorable for the stability after the correction due to certain stress of a jaw dental arch, and is too high in cost. Neither of these methods selectively broaden the arch.

Therefore, it is necessary to provide a regulator having the following features: the correction of class III malocclusion deformity is simple and easy to operate, and the manufacturing cost is low; the invisible and comfortable appearance is beautiful; can also selectively widen dental arch, correct occlusion relation and seal the oral cavity of a patient so as to correct bad habits of mouth breathing, lip biting, tongue spitting and the like.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below to facilitate understanding of the skilled person.

Example 1

Before example 1, the patient was diagnosed by observing the mouth model, and it was found that the partial teeth had abnormal upper and lower jaw coverage. Normal covering of the upper and lower jaws means: the upper teeth cover the lower teeth for a horizontal distance of 2mm. The upper teeth cover the area of the horizontal distance of the lower teeth of less than 2mm, the zone is determined to be corrected through the oral cavity model, namely the upper jaw covers the zone which is not so required to expand the arch, the zone teeth and the alveolar bone are to be corrected in the embodiment: the upper jaw has one tooth at each of its distal end portions, and the remaining teeth and the alveolar bone above them. The stable zone teeth and alveolar bones are: the upper jaw covers the coordination area, one tooth at each end of the upper jaw and the alveolar bone area above the teeth. This patient is the same as most of these patients.

In addition to the above, the following are more frequent in the diagnostic findings of other patients: the tooth and alveolar bone of the zone to be corrected are as follows: the upper jaw has two teeth at its distal end, and the remaining teeth and alveolar bone above them. The stable zone teeth and alveolar bones are: the upper jaw covers the coordination area, two teeth at the two ends of the upper jaw and the alveolar bone area above the two teeth.

As shown in fig. 1 and 2, a vacuum squeeze-film type iii function regulator includes an upper diaphragm 1, a lower diaphragm 2, and a connecting region 3, which are integrally formed with each other. The upper membrane 1 comprises a muscle function barrier area 4 and a stable area 5 which are integrally formed; the muscular function barrier zone 4 is close to the labial and buccal surfaces of the teeth and the alveolar bones of the zone to be corrected, and the inner side of the muscular function barrier zone 4 is 3mm away from the gingiva of the teeth of the zone to be corrected, so that the zone to be corrected is not extruded by muscles, and the dental arch of the zone to be corrected is widened; the upper end of the muscle function barrier zone 4 extends to the vestibular sulcus, and the lower end of the muscle function barrier zone is attached to the occlusal surface of the zone to be corrected. The muscular function barrier region 4 is provided with a buffer region 7 at the frenulum labialis.
